Repsol Honda could regret its decision to sit out the Aragon test come September's race weekend, if Jorge Lorenzo's comments about set-up prove true for෴ the RC213V riders.

Casey Stoner and Dani Pedrosa were the two main absentees from Wednesday's test, which followed a post🅘-race outing at Catalunya on Monday, due to the new-spec front tyre not being made available at Arago𝕴n.

MotoGP World Championship leader Lorenzo led an all-Yamaha top four at the Aragon test, as he put further mileage on a new engine and electr♏onics package, but also claimed it hadn't been easy to dial-in the 1000cc bike.

"This test has b🥃een very important because it's not easy to find the best set-up for the 1000cc bike here as there is so much change from the 800," said Lorenzo, who finished 0.255s ahead of Ben Spies.

The counter a꧑rgument from HRC 🔥will surely be that working on set-up without the tyre spec available for the race is of limited value.

But Yamaha also had new components test and while the revised electro🐎nics seem popular, the engine is less cleℱar cut.

"We tried the engine again ♎like we did in Barcelona, there wasn't so much difference so the engineers now have to make a decision for moving forward," sad Lorenzo, who holds a 20-point lead over reigning champion Stoner after five rounds.

"T🏅hey will consider the data from today to help them."

Lorenzo's best lap, of 1m 49🐬.187s, was just a fraction outside the official lap record set by Stoner in last year's race.

For Spies, who led the majority of the day, the test marked a further chance to rebuild his confidence after a toug🦩h start to the year.

"Today was a good test, to come back after not such a fantastic race on Sunday🌄 and be consistently fast here and in the Catalunya test is important," sai📖d the Texan.

"We've worked really well with the bik♑e and ﷺthe electronics and just tried to change a few things and fine tune.

"The track was a lot better than we thought, we were expecting it to be quite dirty but it wasn't. I feel like I'm getting back up to the potential of the bike and myself which is good."

The Factory team-mates were followed on the timꦕesheets♊ by satellite riders Cal Crutchlow and Andrea Dovizioso.

The Araꦉgon race weekend, round 14 of the 2012 season, will take place from September 28-30.

Lorenzo and Spies will be back in action along their MotoGP rivals during the Briti꧋sh Grand Prix at Silverstone next week💛end.

Tཧhe new spec front, already popular with the Yamaha riders, will become standard from Silve🌳rstone.
